> "biosynthetics" You're probably thinking of biologics [1]. These include immunosuppressant monoclonal antibodies such as adalimumab (Humira) and secukinumab (Cosentyx), used in treating autoimmune diseases such as psoriasis, ankylosing spondylitis, psoriatic arthritis, MS, Crohn's, etc. They are derived from biological sources such as Chinese hamster ovary cells [2]. They are also extremely expensive -- often several thousands of dollars per month [3].
